Python easy_install 抛出 chmod 错误

Question

我正尝试使用来自 Getting Python and Fabric Installed on Windows 的指南在 Windows 7 上安装 Python Fabric .

为了安装 PyCrypto 和 Fabric，我按照指南中的建议使用了 easy_install，但都失败了，返回了一个 chmod 错误:

Using c:\python27\lib\site-packages\fabric-1.3.4-py2.7.egg  
Processing dependencies for fabric  
Searching for pycrypto>=2.1,!=2.4  
Reading http://pypi.python.org/simple/pycrypto/  
Reading http://pycrypto.sourceforge.net  
Reading http://www.amk.ca/python/code/crypto  
Reading http://www.pycrypto.org/  
Best match: pycrypto 2.5

Running pycrypto-2.5\setup.py -q bdist_egg --dist-dir   c:\users\birgit\appdata\local\temp\easy_install-nzrlow\pycrypto-2.5\egg-dist-tmp-_pwkm4  
The command "chmod" is spelled wrong or could not be found.

Traceback (most recent call last):
 File "C:\Python27\Scripts\easy_install-script.py", line 8, in <module> load_entry_point('setuptools==0.6c12dev-r88846', 'console_scripts', 'easy_install')()  
 File "C:\Python27\lib\site-packages\setuptools-0.6c12dev_r88846-py2.7.egg\setuptools\command\easy_install.py", line 1712, in main  

 [... lots and lots of lines... (if they are relevant, I'll post them)]

 File "C:\Python27\lib\distutils\dist.py", line 972, in run_command cmd_obj.run()  
 File "setup.py", line 269, in run  
RuntimeError: chmod error

我不太了解这个 chmod 东西，但我认为 Windows 中没有 chmod？

如何让 easy_install 真正起作用？

我发布了一个类似的问题here ，在那里(感谢@J.F. Sebastian)我找到了一个解决方法来安装那些没有结构的包。但现在我确实想知道如何真正解决我在使用 easy_install 时遇到的问题。

Download并安装 MinGW - Minimalist GNU for Windows。

要使某些 Unix 命令可以从 Windows 控制台访问，请在您的 env 变量中设置:

C:\MinGW\bin;C:\MinGW\mingw32\bin;C:\MinGW\msys\1.0\bin;C:\MinGW\msys\1.0\sbin

.

或者，从控制台:

PATH=%PATH%;C:\MinGW\bin;C:\MinGW\mingw32\bin;C:\MinGW\msys\1.0\bin;C:\MinGW\msys\1.0\sbin
